To all whom it may concern: 1

' Be it known that T, JOHN P. GRANT, a citizen, of the United States, residing at Grandy, in the county of Isanti and State of Minnesota, have invented certain new and useful Improvements in Stable-Cleaning Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper tains to make and use the same. 7

My invention has for its object to provide an improved stable cleaning apparatus; and, to this end, it consists of the novel devices and combinations of devices hereinafter de scribed and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts-throughout the several views.

' Referring to the drawings :-Figure 1 shows a fragmentary view of a barn structure having applied thereto, in working position, the invention, some parts being broken away, and some parts being shown in section; Fig. 2 is a transverse section taken through the barn gutter on the line X X of Fig. 1, and also showing the scraper in rear end elevation; Fig. 3 is a perspective view of the scraper, on an enlarged scale; and Fig. 4 is a perspective view of the rocking bridge.

Of the parts of the barn structure illustrated, for the purpose of showing the invention applied in working position, it is only necessary to note the wall 1, floor 2, stall platform 3, and gutter 4c. This gutter 4% is built in the floor 2, back of the stalls, transversely thereof and discharges into the barn-yard 5 in the wall 1'.

Arranged to travel in the gutter e, is a.

scraper 7 of novel construction. The width of this scraper 7 is substantially the same as that of the gutter 1, and its upper edge portion does not project above the gutter. The scraper 7 is a skeleton structure, having open bottom, sides and rear end. The bottom of the scraper 7 is constructed from a. pair of angle irons 8, and flat intermediate bar 9, and front and rear plates 10 and 11 respectively. The angle irons 8 are laterally spaced, havetheir horizontal flanges turned toward each other, and are rigidly connected, at their respective ends, by the plates 10 and 11, which are riveted,'or otherwise rigidly secured, to the horizontal flanges through an opening 6, formed of the angle irons. The intermediate bar 9 extends parallel to the angle-irons 8 and is ri idly connected, at its ends, by rivets, or otherwise, to the plateslO and 11. The back of the scraper 7 comprises an upright rectangular frame 12,connected at diagonally opposite corners by a pair of cross bars 13. As shown, the frame 12 is bent from an angle iron-and is rigidly secured to the rear ends of the angle irons 8 and to the plate 11.

Each side of this scraper 7 comprises a long bar and a short bar let rigidly connected to the upper-ends'of the sides of the frame 12, and to the vertical. flanges of the angle irons 8.

A. draft cable 15 is attached to the two upper corners of the frame 12 by apair of branch cables, or chains, 16. A spacing bar 17 connects the forward ends of the branch cable 16, in the vicinity of the cutting edge of the scraper 7, and holds said branch cablesin parallel arrangement directly over the sides of the scraper. 7 These branch cables 16 assist the sides of the scraper '7 in holding the'load. The forward end of the cable 15 is extended through the Wall openmg 6 and is provided for drawing'the scraper through the gutter 4 to an unloading position. A draft animal may be attached to the cable'15, or said cable may be 'woundon 'a Windlass drum operated either by hand or power.

To permit the load, within the scraper 7, to be deposited at a predetermined distance from the barn, there is provided a bridge 18 having laterally spaced sides 19. This bridge 18 forms an extension of the gutter V 4:, and, in cross section, is substantially the same size as said gutter. The bridge 18 is fulcrumed on roller 20v for rocking move ment and a limited endwise travel. The roller 20 is journaled, at its ends, in a pair of braced posts 21. The bridge 18 is nor mally supported on the roller 20 in anupwardly and outwardly inclined position, 1 with its lower edge substantially in line with the bottomof the gutter 4L A guide roller 22, forthe cable 15 and branch cable 16, is gournaled in the sides 19, and is spaced above the bridge 18 a suflicient distance to thereunder. An angle bar 23, secured to V and depending from the under side of the bridge 18, engages the roller 20 andlimits the outward travel of said bridge. In draw permit the scraper 7 to pass tion, as indicated by broken lines in Fig. 1.

In this position of the bridge 18 the same will continue to travel with the scraper 7' until. stopped by the engagement of the angle iron. 23 with the roller 20. As the bric 18 is stopped in its travel, the scraper 7 will continue its travel and pass from the bridge 18. In the passing of the scraper 7 from the bridge 18, the load will drop through the bottom of the scraper and be deposited on the pile in the barnyard.

If desired, a wagon may be placed under the outer end portion or" the bridge 18, so that the load from the scraper 7 will be deposited in the wagon instead of the barn yard. It is, of course, understood that the bridge 18 may be permanently secured in position, or the outer end thereof may be supported onthe pile in the barnyard. In barn structures having stalls in the basement, the brid e 18 may be located in the basement in a position. to elevate the scraper T in passing from the gutter to the elevation in the barnyard. In case the gutter 4: discharges through a door opening, as is a case in some barn structures, a draft animal. may

be attached to the scraper -7, driven through the barn, and out of the door opening.

The above described invention has, in

actual usage, proven highly eflicient forthe purpose had in View. 7

What I claim is 1. A barn structure having a builtin gut ter, in combination. with a stable cleaning apparatus comprising a scraperarranged to travel on the bottom of the gutter and hav-. ing a cutting edge and an open skeletonibot tom rearward of its cutting edge, the bottom of the gutter closing the bottom of the scraper during the filling thereof and its movement through the gutter, of a draft device having branch cables secured to the backof the scraper, and a spacing bar connecting the branch. cables in the vicinityof the cutting edge of the scraper and holding the same over the sides of the scraper.-

2. A barn structure having a gutter, in combination with a stable cleaning apparatus comprising an open bottom scraper, arranged JOHN P. GRANT.
